Figure 13 – Location of LED Status Indicators inside the enclosure
LED STATUS INDICATORS – Models 2995 contains two LED status indicators on the printed circuit board inside the enclosure. One LED is a green Power On indicator (PWR) that indicates the presence of the bus voltage and the operation of the main control logic power supply.
The other LED is a tricolor lamp (ST) that indicates a fault or abnormal condition. The information provided can be used to diagnose an installation problem, such as incorrect input voltage, overload condition and control circuit miswiring. It also provides a “normal” signal that informs the user that all control and microprocessor operating parameters are proper. The meaning of the different colors and flash frequencies are explained in Table 5.
